Abstract

CASE DESCRIPTION:

A 5-year-old castrated male domestic shorthair cat was examined because of presumptive lidocaine intoxication. Thirty minutes earlier, the cat had received an SC injection of approximately 140 mg of lidocaine hydrochloride (20 mg/kg [9.1 mg/lb]) to facilitate closure of a wound on the left pelvic limb.

CLINICAL RELEVANCE:

IV administration of a lipid emulsion was used in the treatment of lidocaine intoxication in a cat. Rapid infusion of a lipid emulsion may be a therapeutic option for veterinary patients with toxicosis attributable to local anesthetics or other lipid-soluble drugs.
